Package @siteimprove/alfa-style

Description

This package implements support for CSS properties.

Scaffolding

To avoid circular dependencies, the package is organised as follows (from bottom to top) (all paths are relative to src/) :

• longhand.ts: defines the basic class to model longhand properties;
• property/*.ts (part of): individual longhand properties, one per file;
• longhands.ts: wraps all longhand properties in a nice bundle and export convenient types;
• shorthand.ts: defines the basic class to model shorthand properties, depends on the names of longhands as defined in previous file;
• property/*.ts (part of): individual shorthand properties, one per file;
• shorthands.ts: wraps all shorthand properties in a nice bundle and export convenient types;
• style.ts: expose the actual API to manipulate the properties.

Development

To add a new property, create a file in src/property to define the property, then import the file and add the property to the const in longhands.ts or shorthands.ts.
